I add valve into conf/server.xml of my tomcat
and I created the file rewrite.config in conf/catalina/localhost
and I wrote in my file these lines:
RewriteEngine On
Redirect /testapp/?app=global_search#h_global_search /search
but nothing happened...
I want to redirect the URL:
/testapp/?app=global_search#h_global_search
to
/search
Actually I want all URLs that have this structure:
/testapp/....#h_global_search (can be multiple parameters in the query string)
will move to /search?app=1...&...&...
with all query string that inserted in the source URL.
/testapp/....#h_global_search (can be multiple parameter in the query string)
Assuming .... is a query string, not the URL-path?
You can't match the fragment identifier (everything after the #) since this is not sent to the server.
Try the following instead:
RewriteEngine On
RewriteCond %{QUERY_STRING} ^app=global_search$
RewrietRule ^testapp/$ /search [R,L]
The query string is preserved across the redirect in the above rule. So the above will 302 redirect /testapp/?app=global_search to /search?app=global_search. For any query string (and no query string) then remove the RewriteCond directive entirely.
To match any query string (but there must be a query string) then change the RewriteCond directive to read:
RewriteCond %{QUERY_STRING} .

I want to redirect a URL in .htaccess, but want to keep the (dynamic) parameters from the query string at the end of the URL (e.g. ?id=1660, ?id=1661, etc.)
E.g.
https://mywebsite.example/service/viewinvoice.php?id=1660
I want to redirect it to:
https://mywebsite.example/whmcs-bridge/?ccce=viewinvoice.php?id=1660
So basically: https://mywebsite.example/service/viewinvoice.php?id=... needs to be redirected to https://mywebsite.example/whmcs-bridge/?ccce=viewinvoice.php?id=...
I tried this below, without any success
RewriteEngine On
RewriteCond %{QUERY_STRING} (^|&)/service/viewinvoice.php?id= [NC]
RewriteRule ^/?$ /whmcs-bridge/?ccce=viewinvoice.php [L,R=301]
I think this is not the right solution.
Does someone has suggestions?
You need to use the QSA (Query String Append) flag on your rewrite rule. From the documentation:
When the replacement URI contains a query string, the default behavior of RewriteRule is to discard the existing query string, and replace it with the newly generated one. Using the [QSA] flag causes the query strings to be combined.
From your example URLs, you don't need to match the query string in a rewrite condition. You are matching the URL path which is done as the first part of the rewrite rule itself.
Your rule should be:
RewriteEngine On
RewriteRule ^/?service/viewinvoice\.php$ /whmcs-bridge/?ccce=viewinvoice.php [L,R=301,QSA]
Have been trying to write a redirect rule with query string but did not succeed.
I have the URL example.com/blog/?page=1 or example.com/blog/?hello, so it does not really matter what goes in the query string. How do I write a Redirect rule, so that it cuts the query string and redirects to the URL before the query string. For example, both of those URLs have to redirect to example.com/blog/ so that URL does not contain any query string.
I was trying
RewriteRule ^blog/?$ blog/ [R=301,L,NE] but got redirected to 404 page.
Also tried
RewriteRule ^blog/?$ /blog/ [R=301,L,NE] and got the message that page is not working, 'URL' redirected you too many times.
BTW, technology I am using is Gatsby with htaccess plugin.
To remove the query string you first need to check that there is a query string to remove, otherwise, it should do nothing.
For example, to remove the query string from /blog/?<query-string> you would do something like this:
RewriteCond %{QUERY_STRING} .
RewriteRule ^(blog)/?$ /$1/ [QSD,R=302,L]
This matches the URL-path blog/ (trailing slash optional) and redirects to /blog/ (with a trailing slash). Your example URL includes the trailing slash, but your regex appears to suggest the trailing slash is optional?
The preceding condition (RewriteCond directive) checks the QUERY_STRING server variable to make sure this is non-empty (ie. it matches a single character, denoted by the dot).
The $1 backreference in the substitution string contains the value from the captured group in the preceding RewriteRule pattern. ie. "blog" in this example. This simply saves repetition. You could just as easily write RewriteRule ^blog/?$ /blog/ [QSD,R,L] instead.
The QSD (Query String Discard) flag removes the original query string from the redirected response, otherwise, this would be passed through by default (which would create a redirect-loop).
If the request does not contain a query string then this rule does nothing (since the condition will fail).
If this is intended to be permanent then change the 302 (temporary) redirect to 301 (permanent), but only once you have confirmed this works as intended. 301s are cached persistently by the browser so can make testing problematic.
A look at your existing rules:
was trying RewriteRule ^blog/?$ blog/ [R=301,L,NE] but got redirected to 404 page.
By default, the relative substitution string (ie. blog/) is seen as relative to the directory that contains the .htaccess file and this "directory-prefix" is then prefixed back to the relative URL, so this will (by default) result in a malformed redirect of the form https://example.com/path/to/public_html/blog/.
Also tried RewriteRule ^blog/?$ /blog/ [R=301,L,NE] and got message that page is not working, 'url' redirected you too many times.
This is not checking for (or removing) the query string so this is basically just redirecting to itself - an endless redirect-loop.
Remove any query string from any URL
What rule do i write, to remove query string from any URL.
Modify the RewriteRule pattern to match any URL and redirect to the same. For example:
RewriteCond %{QUERY_STRING} .
RewriteRule (.*) /$1 [QSD,R=302,L]
This needs to go at the top of the root .htaccess file before any existing rewrites.
If the .htaccess file is in a subdirectory (not the root) then you will need to do something like the following instead, since the $1 backreference (as used above) won't contain the complete root-relative URL-path.
RewriteCond %{QUERY_STRING} .
RewriteRule ^ %{REQUEST_URI} [QSD,R=302,L]

I am trying to generate an external redirect that involves a few specific tasks.
If specific query string value is found in the URL, redirect.
If redirected, replace one of the query string parameter names but not its value.
If #1 is false, then ignore rewrite and proceed
Example: I have the url http://foobar.com/?a=123&b=456&c=blah
First, if parameter c = blah, redirect to http://barfoo.com/
Second, replace a with x parameter so the final URL is http://barfoo.com/?x=123&b=456&c=blah
Below is my best guess so far after researching on http://mod-rewrite-cheatsheet.com/ and Hidden features of mod_rewrite
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.foobar\.com$ [NC]
RewriteCond %{QUERY_STRING} ^a=(.*)&b=(.*)&c=blah$ [NC]
RewriteRule ^(.*)$ http://barfoo.com/?x=%1&b=%2&c=blah [NC,L,QSA,R=301]
However, the URL is appending the query string, not replacing.
I get redirected to http://barfoo.com/?x=123&b=456&c=blah&a=123&b=456&c=blah
smacks forehead
Removing QSA from the flags solved the issue. QSA means "append the existing query string to the current rewrite rule." It ignores whatever new query string parameters you are adding.
I thought it was needed to have query string parameters exist for the rewrite rule itself.
RewriteRule ^(.*)$ http://barfoo.com/?x=%1&b=%2&c=blah [NC,L,R=301]
I have a link http://mywebsite.com/?view=3457373673863568
everything after the view= will change depending on who gets it.
how can I redirect them to another page on the site i.e. http://mywebsite.com/mypage
something like:
RewriteRule http://mywebsite.com/?view=(?) http://mywebsite.com/mypage/
mod_rewrite parses the URL and the rules only see the path, not the query string. The query string is stored in the variable QUERY_STRING, which needs to be matched separately.
RewriteCond %{QUERY_STRING} ^view=
RewriteRule ^$ /mypage [L]
This matches the empty path (i.e., / on your site) and any query string that starts with view=. The query string will be passed implicitly to the target page.
If you want an external redirect so the user browser shows /mypage, use the [R] flag (change [L] to [L,R]).
